She'd been pulled out of bed early that morning and not even had enough time to change out of her pajamas, thus - as Martha had some more coffee, with a yawn - she was in her nightclothes still with a labcoat thrown over them. It had been a long night, and whole she had the chance to leave to change, she hadn't becuase she did not want to leave her patient alone in this place.
Not the first time she'd been called down on a dire early morning emergency, looking back on it, Martha realized that she should keep a change of clothing in her office, just to be safe.
She'd cleaned and dressed the wounds, sewing up those which needed it. Booth had been in a right state. She'd been told that he was 'dancing' with a demon, but the end result terrified her. He was lucky that he hadn't gotten worse. She was almost certain that the entity could have done more damage if it wanted...
She heard something and put her coffee mug down, walking out of the office and seeing Booth awake. She paid no heed to her state of dress. There were more important things to deal with right now. "How are you feeling?" it was the first and very necessary to ask.
